Surprisingly it isn't mentioned what the characters mean at all. Most of the non-decomposed characters are martial arts related: 功夫 kung fu, 武術 martial arts, 空手 karate, 道場 dojo, 氣 qi/ki (air), 流 flowing, 安 peace, 康 health, 極 the 'chi' from taichi, and 拳 fist. Some even line up with the letter, using Chinese or Japanese pronunciation, e.g. fu from kung fu, jitsu, kara from karate, ryu. The rest seems to be corruption from these building blocks.
